Answer:
<u>Option D : c =200t</u>
Step-by-step explanation:
The number of calories burned C varies directly with the time spent exercising T
∴ ∝ t
∴ c = a t
Where a is the constant of proportion
exercising for 4 hours he burns 800 calories
∴ c = 800 when t = 4
∴ 800 = 4 a
∴ a = 800/4 = 200
∴ c = 200 t
<u>The answer is option D : c =200t</u>
Step-by-step explanation:
z = (x − μ) / σ
z = (65 − 69) / 3.5
z = -1.14
x ≤ 12
Solution:
Let us take the number be x.
A number : x
A number divided by three : 
A number divided by three less two : 
A number divided by three less two is at most two : 
Now, simplify the inequality,
Add 2 on both sides of the inequality,
Multiply by 3 on both sides of the equation,
Hence x ≤ 12.
Answer: 84.09%
Step-by-step explanation:
1. 220-30=? ?=185
2. Divide 185 by 220 (as a fraction, 185 out of 220 is 185/220 which also means divide) 185 divided by 220 is about 0.8409
3. Multiply 0.8409 by 100 (since there is two zeros in 100 we can move the decimal to the right twice which gets you 84.09
